I FUR SEWING MACHINE ATTACHMENT- Filed Oct. 4, 1929 fly liazzer .NVENTOR V \iz ATTORNEY Patented Apr. 19, 1932 UNITED STATES HARRY \IVEISNER, OF PHILADELPHIA,PENNSYLVANIA FUR SEWING MACHINE ATTACHMENT Application filed October 4, 1929. Serial No. 397,294.

The present invention relates to the art of fur sewing machines and more especially to the type known as over-seaming machines for stitching furs, and relates more particularly to an improved attachment carried by a grooved needle guide plate and serving to prevent the edge of the fur material traveling unevenly between the inner and outer feed discs or wheels and hence preventing irregular stitching.

Another purpose is to provide an attachment for the guide plate, integral therewith and serving to guide the edge of the fur material and to prevent irregular stitching in over-seaming, and also to provide an attachment which is very simple, very inexpensive, the cost of manufacturing over and above the costly device now in use being minimized to a considerable extent, and thereby enabling them attainable by all firms or persons using fur over-seaming sewing machines for a very small cost.

It is to be understood that the particulars herein given are in no way limitative, and that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a plan View of a portion of an over-seaming fur sewing machine, illustrating the improved attachment for the needle guide plate applied.

Figure 2 is a detailed perspective view of the needle guide plate removed and illustrating the attachment as'being integrally applied.

Referring to the drawings, 1 identifies the frame of the fur over-seaming sewing machine and 2 and 3 are the inner and outer feed discs or wheels, the peripheries of which are serrated as shown at 4, and between which the fur material 5 passes. A needle guide plate 6 isprovided, and is so associated with the outer feed wheel 8 that the shoulder 7 of Said needle guide plate is adjacent the inner face of the flange of the feed wheel 3. r

The plate 6 has a needle guide groove 8, into which the needle 9 carried by the needle bar 10 enters, the needle operating through the edge of the fur material in order to apply a the stitching.

An arm 11 is formed integral with the needle guide plate 6, and a shown in Figure 2 itis slightly upwardly disposed out of the plane of the upper surface of the plate 6. This arm 11 is also slightly laterally disposed as shown and its under portion has a guide groove 12 into which the edge of the fur material engages as it passesbetween the inner and outer feed wheels, and thereby guiding the fur material so as toprevent irregular stitching, and especially when overs seaming. It is to be noted that the end 'portion of the guard arm beyond the groove 12 overlies the face of the inner feed wheel a substantial distance at all times and when operating on the work, the under face of said end portion-beyond the groove is arranged in extreme close position to the face of the inner feed wheel, so as to prevent the fur as well as the material from lapping over the face of the inner feed wheel, and thereby further avoid irregular stitching.

The arm 11 is the essential improvement, namely to guide the fur material and prevent irregular stitching. However the description herein in connection with the drawings, merely sets up enough of the old construction of a fur sewing machine, in order to illustrate the application of the present invention.

I claim:

In a fur seam sewing machine having inner and outer feed wheels, between which the marginal portion of the fur material passes when being stitched, a guide for the material consisting of a needle guide plate operatively associated with and extending from the 'cen'-' ter of the outer feed wheel towa-rd said needle, the under surface of the plate nearest its free end conforming to the adjacent portion of the outer feed wheel, said needle guide plate having a guard arm carried by one corner of said plate and offset from alignment with the needle, the under face of the guard arm having a rectangular groove immediately adjacent to and in alignment with the spacebetween the inner and outer feed wheels and adapted to receive the edge por- V tion of the fur material, thereby guiding the material and preventing irregular stitching, the end portion of the guard arm beyond 'm the groove overlying the face of the inner feed wheel a substantial distance at all times and when operatingon the work, the under face of the end portion beyond the groove being in extreme close position, to the face of the inner feed wheel, thereby "preventing the 'fur as well as the; material from lapping over the faceof the inner feed wheel, thereby further avoiding irregular stitching.

In testimony whereof he afiixes his signa-.

ture.
